instinctively
UK: ɪnˈstɪŋktɪvli | US: ɪnˈstɪŋktɪvli
adv. in a way that is driven by innate, automatic behavior or natural impulse
adv. without conscious thought; spontaneously
The word "instinctively" derives from the Latin instinctus ("impulse, inspiration"), combining in- ("upon") + stinguere ("to prick, goad"). The root "instinct" evolved to denote innate behavioral patterns in animals and humans. The suffix "-ive" forms adjectives indicating tendency or capacity, while "-ly" converts it into an adverb. Thus, "instinctively" literally means "in a manner driven by innate impulse," reflecting automatic, unlearned responses.

Babies instinctively grasp objects placed in their hands.
